Penegra 100 mg (Sildenafil Citrate)

Product Overview

Penegra 100 mg is a prescription medication that contains Sildenafil Citrate, the active ingredient used worldwide to treat erectile dysfunction (ED). Manufactured by Zydus Cadila Pharma, each strip includes four tablets of 100 mg strength. Pack sizes available are 60, 120, 180, and 240 tablets, allowing patients to select the quantity that best fits their treatment plan. Delivery typically takes 6 to 15 days depending on the shipping destination. This product is intended for adult men with diagnosed ED and should be used under medical supervision.

What is Penegra 100 mg

Penegra 100 mg belongs to a class of medicines known as phosphodiesterase type 5 inhibitors. The active ingredient Sildenafil Citrate works by relaxing the smooth muscle in the penile region, which increases blood flow during sexual stimulation. This mechanism helps men achieve and maintain an erection sufficient for satisfactory sexual activity. The medication is not an aphrodisiac and does not increase sexual desire; it only supports the physiological response when a man is sexually aroused.

Uses and Benefits

The primary use of Penegra 100 mg is the treatment of erectile dysfunction, a condition that affects millions of men globally. Clinical studies have demonstrated that Sildenafil Citrate improves erectile function in a majority of patients, with onset of action typically within 30 to 60 minutes after ingestion. Benefits include enhanced ability to achieve an erection, increased confidence during sexual activity, and improved overall sexual satisfaction. In addition, some patients report a modest improvement in exercise capacity due to the vasodilatory effects of the drug, though this is not the intended purpose of the medication.

How It Works

Penegra 100 mg inhibits the enzyme phosphodiesterase type 5 (PDE5), which normally breaks down cyclic guanosine monophosphate (cGMP) in the penile tissue. By blocking PDE5, the drug allows cGMP to accumulate, leading to relaxation of smooth muscle and dilation of blood vessels. This physiological response increases blood flow to the penis, facilitating erection when sexual stimulation occurs. The effect lasts for approximately four to six hours, providing a window for spontaneous sexual activity. It is important to note that the medication does not produce an erection without sexual arousal.

Dosage Guidelines

Penegra 100 mg should be taken orally as needed, typically about one hour before anticipated sexual activity. The tablet should be swallowed whole with a full glass of water; it may be taken with or without food, although a high‑fat meal can delay absorption. According to the U.S. Food and Drug Administration (FDA) guidance, the recommended starting dose is one tablet per day, and the dose should not exceed one tablet within a 24‑hour period. Patients with certain medical conditions or those taking specific medications may require a lower dose, and they should consult a healthcare provider before adjusting the dosage. It is essential to follow the prescribing information carefully to avoid potential complications.

Side Effects

Like all medications, Penegra 100 mg can cause side effects, although many men experience none or only mild symptoms. Common side effects include headache, facial flushing, nasal congestion, and mild dizziness. Less common but more serious adverse events may include sudden vision loss, hearing impairment, or priapism — a prolonged erection lasting more than four hours. For more detailed information on potential adverse events, see the National Institutes of Health (NIH) resources. If any of these serious symptoms occur, medical attention should be sought immediately. Patients should also be aware of potential interactions with nitrates, alpha‑blockers, or other PDE5 inhibitors, which can lead to a sudden drop in blood pressure.

Warnings and Precautions

Penegra 100 mg is contraindicated in individuals who are allergic to Sildenafil or any of the inactive ingredients of the formulation. Patients with severe cardiovascular disease, uncontrolled hypertension, or a history of recent stroke or heart attack should discuss their medical history with a physician before use. The medication should not be used in patients taking nitric oxide donors, such as nitroglycerin, due to the risk of severe hypotension. Alcohol consumption should be limited, as it may increase the likelihood of side effects. Finally, the drug is intended solely for adult men; it is not approved for use in women or children. For additional safety information, refer to the MedlinePlus (MedlinePlus) database.
